additional information | substitution of the AUG initiator of the mitochondrial ValRS isozyme, ATG1 of VAS1, with redundant ACG triplets, mutation of ATG1 to GCG deprived the construct of its mitochondrial activity, redundant ACG triplets could effectively substitute for ATG1 in initiation of the mitochondrial enzyme, while a single ACG triplet could hardly do so | Saccharomyces cerevisiae |
